Verified live 2026-10-19: Tamid's own example for POST /chatzer/sanhedrin
(a case with `sides`) answered 500. The router passed the sides LIST as
the case context; halt_monitor:check_avodah_zarah/1 reads a map, maps:get
raised, and the halt monitor and escalation gen_servers died with the
caller's input (supervisor restarted them; health stayed 8/8). The router
then matched {:ok, decision} on the error and made a 500 of its own.
- sanhedrin/src/halt_monitor.erl: do_check_case refuses a non-map
context as {halt, malformed_case, _} and stays standing. EUnit 49/0
with the new halt_malformed_context_test.
- router.ex process_sanhedrin: sides validated at the kiyor (422 on a bad
shape), carried as context %{sides: sides}; a Sanhedrin refusal answers
422 SANHEDRIN_HALTED, a failure 503 SANHEDRIN_UNAVAILABLE. Two new
router tests, one asserting the gate processes survive the example.
Elixir 624/0.
- specs/broken_tablets/README.md: tablet 55, including what is NOT fixed
— a panel of one accepting on zero references under a grounded-
sounding sentence, the ignored complexity hint, no panel manna spent,
no L3 record. The row in Tamid is still larger than the thing behind it.
Doorpost pin unchanged (no @spec_files touched; scripts/doorpost_check.py
passes).
